Description

What's the differences from "Full Covered Sizes" and other sizes - "Non Full Covered Sizes"? Hi, Full Covered Sizes are meant to cover all the bed, they are designed from 72 inches long and suits most bed having lengths such as 190cm and 200cm. Should I measure my beds before making order? Hi, It is highly recommended to measure your real beds before buying. After measuring your bed, you could decide to buy a full covered size or a normal size, such normal size is only covered half or more of the bed. Will the width of the product I purchased be exactly as described? There is no international standard for bed edge design. To ensure a perfect fit with bed frames, we've reduced the width of some products by 1 to 1.5 inches. This won't affect daily use and actually makes installation easier for consumers.

    • Great upgrade for a sleeper sofa. Great upgrade for a sleeper sofa.
Size: (56.5”x76” Queen Size)
Review Image by T. M.
We eliminated our guest room and got a sleeper sofa as an optional spare bed for visitors. While looking around on Amazon for ways to improve our sofa bed, this item was suggested to me. I never knew something like this existed but I bought it on whim to try it out. It’s easy to use but a little bulky to move around by yourself so you may want to have someone else present to help you. It’s sturdy, prevents the springs and various support bars in a foldout couch from digging into your back. Our guests stated they slept well. Our sleeper sofa is a queen size. I didn’t measure anything and thankfully this fit perfectly. It was the exact size needed. It was actually a little longer than the mattress but he added height prevents the foam mattress from folding over the edges. When you’re done it folds up and stores easily in a closet or behind the couch. (You can’t fold it in with the mattress, unfortunately.) We kept the original box because we move a lot and I’d be concerned how it would hold up in an move without the outer box protecting it. Overall, I would recommend this product. Especially if you plan on sleeping on your sofa bed regularly. ... show more

    • MEASURE BEFORE ORDERING BUNKIE BOARD MEASURE BEFORE ORDERING BUNKIE BOARD
Size: (32”x58.5” Small Twin Size)
Review Image by Carla B
Better yet.. Just skip this product. I ordered this for a twin size loft bed. I’ve never really had to measure stuff for a bed. These are pretty basic measurements, so I ignored the reviews and took a chance. It was obvious out the box that this bunkie board was too small. Just quickly measuring for reference, but close enough. The board measures about 33”W x 58”L .. the bed measures about 40”W x 77”L .. It’s not even close. This would probably fit my toddler’s bed. Their full size would almost fit a twin except it’s 48”W.. Close, but nope. The fabric that covers the board seems decent quality and definitely stays in place, but it’s baggy, so once the mattress was placed on it, the fabric kind of sags through the bars. We needed the board asap, so I could try and see if it will work, but I’m returning it because since it only sits in the middle of the frame, it made it sag even more. For the seller: A bunkie board should fit the entire frame for extra mattress support. It’s wrong to advertise and sell a product that you know isn’t going to fit. The picture shows how much smaller it is than the bed itself. ... show more

    • Stable and secure!
It's just what I was looking for to go between my mattress and platform bed. Now there's no more creeking when I get into bed and it's firmer too! Great buy for me.

    • Meh — Slightly Better Than Nothing, But Not by Much
Size: (56.5”x76” Queen Size)
The NobleRealm® Better Size Sleeper Sofa Board is... fine. It does make the pull-out couch a bit more comfortable, but don't expect a miracle. You can't feel the bars underneath, but it's still not terribly comfortable. Probably more of a mattress thing.... What really threw me off was the chemical smell straight out of the box—strong and unpleasant. In short: it’s marginally helpful. ... show more

Disappointed in the size ordered full but seems like it's more for a twin should have checked the measurements before I ordered

    • Not what is pictured
Size: (46”x76” Large Full Size)
I have bought boards from another before and know they never fit the mattress fully so that I was already expecting. But what I got was not what was pictured. Whata pictured looks a lot higher quality than what I received and thats what im not pleased with. It will still work. But when you show something that looks a lot higher quality than what you send. In the picture it does look like the boards are in a nice fabric that fits the boards snug. But what I got, the fabric feels cheep and is covered in rubber dots that will fall off over time from when I flip and rotate the mistress and the cover fits VERY loose on the boards. ... show more
